t4 turbo, is this kit any good ?

[golf-sib]

Sounds interesting, definitely will head down the t3/4 route.

Regarding water injection, any kits you recommend, as some information may give me an idea on possibly doing this in the future.

Interesting thing with the downpipe, T3/4 exhausts at the top i think, not sure if you can get these any cheaper anywhere..

Pressume you would only need the 'U' bend

Not going to tell the exact spec yet, as I have spent the last four month working on the turbo. I found not all parts are equal even in ko3s parts vary between batches.  It's basically the aggressive turbine side from the k04-001,  with one of the bigger comp wheels from a ko3s, plus machine work on the comp housing, wastegate and back plate. There is another generation comp wheel that I am going to try just to see if I can loose a more low down torque and give a even greater area under the curve at the top end.

As for clutch I am running the stock oem dmf and clutch set up, so cannot comment on the vr6 solid setup, but I have known the solid conversion to suffer with stage2 ko3s mapping in the past, but never looked in to why it was slipping under load. You need to do some research on the solid setup and see what people are actually pushing from them and where the peak torque is rpm wise.

vr6 clutch slipping... first I've heard of it, why is it such a popular conversion as I thought the DMF wasn't that durable and the figures of the vr6 clutch where superior. Be good to find out more about this as I think this would be a shocker.

All interesting and first I have heard of it.

Alse here's your pics:

Cheers for adding the pics.

As for the solid conversion that was slipping we never found out what kit was used, oem, 3rd party or eBay solid deal kit. So I cannot comment on it until I actually use one or map an oem kit with big power.  It's the low down torque where the clutch suffers slip. I know the cheap dmf kits from CAS slip with 225lbft straight out the box. My next clutch setup will be sachs fast road organic clutch with oem dmf

[golf-sib]

Be good to know your findings as I am on the sachs vr6 clutch and ecs 14lb flywheel.

Any info on meth/water kits you guys running and are they easy to install and how do they operate (as in are they like a carburetor where as air flow increases so does the water, or is it managed by a separate unit that takes a reading etc?).

The kit I had in mind to make had a pressure switch in the inlet which activates a washer bottle motor. then the water is fed to a nozzle that injects the water as a mist... The Renault 5 GT turbo has an adjustable pressure switch on it that can be used

Most things we buy nowadays are made in china arent they?? they all have to be made to a decent quality for people to be able to sell them dont they.. you cant sell something that is going to blow when you push it to the quoted figures they have provided? 

No steer clear imo

Have you have tried and tested one?

We have tried and tested many cheap turbos from ebay, xs-power ssautochrome and all made good power and lasted the duration. One was a T34/s5 running at 508bhp@1.7bar another 1.5bar 470bhp,  T3/04e 404bhp@1.7bar(£140 turbo from ebay)  k04-001 240bhp.

Its down to how they are tuned and heat generation, and even if it blows in the 1st year its only going to cost £140 for a new one, and not £1k+ for a oem.

Done right they are worth the money IMHO.

No i have not BUT i have always been told, by everyone ive ever spoken to avoid Chinese turbos. Its not a route i would go down i want reliability and piece of mind - that's just my opinion.

But hay if you have tested them and say they are ok then go for it people

like i said, the people who buy the cheap turbos usually buy other bits on the cheap, if a turbo goes pop theres most likely an underlying cause. also even oe turbos go pop

Devils own stage 2 kit is the one I use, google it.  Water injection needs to be mapped correct, Ie lean running fuel map strategy more ignition advance at peak cylinder pressure.  Running the fuel at stage 2 or even stage1 12.5:1 / 11.5:1 will reduce power, but still give good cooling.   I am running 13.5:1 under load from 3000rpm to 7800rpm with around 4deg more advance than any other mapped 1.8t would run. I am seeing ignition pull of 4-5cf at 3500rpm at 22psi, without the water injection the Ignition correction would be pulling +12cf, with loud audible knock/pinking and on the verge of piston or spark plug damage.  I can thrash my car hard for 3 hours, then straight away lift the bonnet and put my face on the inlet manifold which will be as cold as a can of beef of of the fridge.


We also used it on a mondeo tdci with nos and managed over 100bhp 130lbft gains on the stock turbo, it's the water injection which maintained the power across the whole rpm range.  Should be in the fast ford mag soon, once if the quickest 130tdci in the uk. :-)
